Group 5 element

A Group 5 element is one in the series of elements in group 5 (IUPAC style) in the periodic table, which consists of vanadium (V), niobium (Nb), tantalum (Ta), and dubnium (Db).

All of these elements are classed in Group 5 because their valence shell holds five electrons. Dubnium can only be produced in the laboratory, and does not exist in nature.

Biological occurrences

Of the group 5 elements, only vanadium has been identified as playing a role in the biological chemistry of living systems: it is involved in some of the enzymes of higher organisms, and also, unusually, in the biochemistry of some marine tunicates.
